SLED-BRAK.

SPECIFICATION forming part of Letters Patent No. 399,405, dated March 12, 1889.

Application filed June 2l, 1888. Serial No. 277,854. (No model.)

To all whom it may concern,.-

Be it known that I, CLARENCE EUGENE HOLLEY, of Fort Faireld, in the county of Aroostook and State of Maine, have invented 5 a new and useful Improvement in Sled-Brakes,

of which the following is a specification.

This invention pertains to certain improvements in brakes for sleds, having' for its objectto elect the retarding of the movement 1o of the sled or preventing the accelerated movement thereof on downgrade, while the tongue or shafts are capable of bein g elevated out of the way when the sled is out of use and to equalize the application of the pressure i5 or force exerted in applying` the brakes; and

to these ends the nature of the invention consists of a central sliding; plate or bar having connection with the brakes or shoes and with the tongue or shafts, so as to effect the requisite movement of said central sliding; plate or bar; and it consists, seeondly, of the central bar or plate having a whiffletree-like connection willi the brakes or shoes and having its forward end stepped or angular and provided with a slot which receives a stud or projection on a rearward extension of the pole or tongue, and, finally, ot' a whilii etree connect ed io said ventral sliding bar or plaie, and the draft elips or hooks connected to said whiille- Iirame, all substantially as ln'groinai'ler more full)T set .iforth and claimed.

In the accompanying' d rauines, Figure l is a plan view et' a sled emlnidying' my improvenient. Fig'. is an under side view ol the same, and Fig'. Il is a loneitlnlinal section ihereot'.

In (':lrrying' out my invention, I apply eentrally olf the sled. A, in the direction of its 4o length, a bar or plate, l5, the same having,` a

sliding movement in keepers or staples l) l), i,

secured to the under side ot' cross-bars o (ly a. ot the sled-frame. The rear end of the bar or plate l.; is turned up or otherwise adapted This longitudinal bar or plate B is about centrally connected or pivoted to a whiiidetreelike eoiineetion or cross-bar, e', by means of to form a stop, n, which limits its forward g movement by Contact with a (cross-bar, a.

an angular plate or keeper, ("3, riveted or 5o bolted at one end to said plate or bar B, and receiving a nutted bolt, ci", passing` through the plate or har B and the connection e. The cross-bar or connection of has applied ject beyond its ends, plates d, each of whiehv is provided with an aperture, d', the purpose of which will appear further on.

C C are the brakes, each of which consists of an elbow-lever pivoted at its angle to a 6o runner of the sled upon the inside oi' the latter. The lower ends oi the levers are each broadened into a proximately chisel-point shape, which is adapted to take into or have the required fric-tional Contact. with the sur- 65 face. The upper ends of the levers are prei` erably rounded or made eylindric and passed through the apertures d in the plates CZ of the eonnection or cross-bar C', permitting' of the requisite articulating movement between said 7o parts as the brakes are operated. The forward end ot' the longitudinal bar or plate B is stepped or lient, as at ll', one (the vertical) arm olf which stepped portion L forms, in connection with the cross-bar o', astop tor limit- 75 ing the rearward movement of the said plate or bar li. The horizontal arm ot said stepped portion l1 oli the bar or plate l?) is provided with a slot, L?, the tuin-tion ot" which will be seen presently.

D is the tongue or polo, whiehhasa sliding` connection with the [fronthounds, i",which has s, j, pivoted l its rear roekin g cross-piece or r l in the upper forward ends of the sled-runi ners. The rear or inner endof the tongue or 85 pole D is formed with a reduced rearwardlyextending portion, D, which has applied to its under side a plate or (fasting, D?, also litting,1 upon the rear end ot said extension or portion D', and formed upon its under side 9o i with a sind or projection, d'2. This stud or I projection (l2 enters the slot Ik of the stepped l portion ot' the plate or bar B. Longitudinal movement or play is provided for the studor projection d2 of the casting or plate D2 by 95 l forming' a slot or recess, g, in the under side of the rocking,` rear cross-piece or axis, f, of

l the tongue-hounds D and forming` a recess or and fastened to its under side, so asfto pro- 55' slot, g2, in a clip or keeper, g', bolted to the under side of said axis or cross-piece f across the recess or slot g.

E is a whifiietree connected to the longit-udinal endwise-niovable bar or plate B, near the forward end of the latter and adjacently to the cross-bar d', and having applied to its ends the draft or hooked clips or loops F E, through which passes the cross-bar a.

In operation, it will be observed that upon the team being held back, as is practiced upon a downgrade, the tongue or pole will have a rearwardly-sliding movement, which will cause the stud or projection d2 of the casting or plate D2 of the tongue-extension D to act upon the plate or bar B, so as to move the cross-bar or connections c in such a manner as to effect the application of the brakes C C. As the team gains or reaches a level, it will be seen that the holding back of the same being unnecessary, permitting it to regain its former movement, the tongue or pole is thereby drawn forward, which will have the reverse effect upon the other parts from that above described, whereby the brake will be thrown out of operation or use.

Having thus fully described my invention, what l claim as new isl. The combination of the endwise or longitudinally movable plate or bar having connection with the longitudinally-movable tongue, with the brakes having a whiletreelike or cross-bar connection with the longitudinally-inovable bar or plate, substantially as and for the purpose set forth.

2. The sled-brake comprising the central or longitudinal endwise movable plate or bar and the proximate Whiffletree-like connection or cross-bar between said plate and the brakes, substantially as set forth.

3. The sled-brake comprising the longitudinal plate or bar actuating the brakes and having a stepped slotted forward end, and the sliding tongue or pole having a pendent stud or projection engaging said stepped slotted end of the longitudinal bar or plate,

substantially as specified.

4. The sled-brake comprising the longitudinal endWise-Inovable plate or bar actuated by the tongue or pole and having connection about at its mid-length with a cross-bar about at its center, which cross-bar is provided at its ends with apertured plates, and the elbowlever brakes having their upper ends entering the apertures of the end plates of said cross-bar, substantially as set forth.

5. In a sled-brake, the combination, with the endwise-movable plate or bar having a slotted stepped forward end and carrying about at its middle a cross-bar having apertured end plates which receive the upper ends of the brake-levers, of the sliding tongue having applied to its reduced rear end or extension a casting or plate provided with a stud or projection entering the slotted stepped forward end of the endwise-inovable plate, and the whiffletree provided with the hook-clips, substantially as specified.
